CARRIAGE FOB snnr nc'rme MULES.

Application filed February 22, 1!?21. Serial No. 446,988.

To all whom it may concern: v

Be it known that I, HENRY PLATT HALL, a subject of the King of the United Kingdom of Great- Britain and Ireland, and resident of Taravon WVerneth, Oldham, in the county of Lancaster, England, have invented new and useful Improvements in Carriages for Self-Acting Mules, of which the following is a specification.

This invention relates to carriages for self acting mules whether constructed wholly or in great part of steel or other metal plate or sheet or of wood and consists in devices which in comparison with devices section thereof and made to bear a bearing 7 bracket for the tin roller and a block through or to which is attached a screw foradjusting the bearing bracket lengthwise of the channel bar;

Such a channel bar used for bearing a bearing bracket and a block to receive engagem'ent or attachment of a screw as afore said, having parts of the flanges of the chan-' heretofore employed for the like purposef' nel bar made to furnish at the ends ears at facilitate the application of carriage bearers on carriages of'self acting mules and bearing brackets for tin roller shafts on carriages of self acting mules so constructed.

For the attainment of these advantages, the invention consists in devices and constructions to be applied in carriages as aforesaid, which are hereinafter to be described and particularized in the claims,

but before reference in detail is made to the several devices and constructions, indication of their general nature will be given by saying the following are comprised in the invention Steel or other channel bars applied flanges upwards,transversely on the bottom of the carriage of a self acting mule or a section thereof and furnished with rising screws for the connection of a carriage bearer; such channel bars which have parts of the flanges made to extend as ears transversely from their ends and are riveted or bolted .to angle bars or flanges riveted or otherwise secured or provided on the bot-- tom of the carriage or section;

Such channel bars with ears riveted or bolted to angle bars or flanges riveted or otherwise secured or provided on the bottom of the carriage or section or sections and extending along it or them; 4

Such channel bars with ears riveted or bolted to angle bars riveted or otherwise secured or provided on the bottom of and extending along the carriage or section or sections and provided with holes at equal intervals along their length;

Channel bars as aforesaid with holes and communicating slots serving respectively for the passage of the heads and for the passage of the shanks of rising screws;

right angles to thebar or'in other positions convenient for the attachment of the channel bar; I

Such a channel bar used for hearing a bearing bracket and a blockto receive engagement or attachment of a screwas aforesaid, having a hole and communicating slot or holes and communicating slots for the passage of the heads and shanks of bolts,- for-securing the bearing bracket for the tin roller or the block or the bracket and block to the channel bar.

This invention is illustrated in the accompanying drawings as applied in a carriage for a self acting mule constructed of steel or other metal plate or sheet in the form of sections constituting when complete a continuous box girder as described in the specification of another application filed on the same day as this and provided with removable rests for the spindle rails or boxes as described in the specification of yet another application filed on the same day as this, Figs; 1 and 2 illustrating theprovision on such carriage of means according to this invention for facilitating the application of carriage bearers and Fig. 3 illustrating'the provision on such a carriage according to this invention of means for facilitating the application of bearing brackets for tin roller shafts. Fig. 1 is a transverse section through part of the carriage of a self'acting mule showing in side elevation part of one of the carriage bearers and the means by which it is secured to the'carriage. Fig. 2 is a front elevation of some of the parts tion through part of the carriage of a self acting mule showing in side elevation one a of h e g bra kets for the tin roller shown in Fig. 1, Fig. 3 is a transverse secany manner convenient. glebars and brackets slmilar to those shown shaft and the means by which the bracket shown is fixed in position.

The same letters of reference are employed to indicate corresponding parts in all the figures.

The mule carriage, parts of which are shown in the several figures, is formed in sections or lengths each of which is formed of a lower steel or other metal plate or sheet bent to form the bottom a and to provide upwardly turned flanges I) 0 forming the front and rear walls of the section and an upper steel or other metal plate or sheet bent to form the top 05 of the section and upwardly turned flanges e f at the front and rear riveted on the front I) and back 0 of the section. The sections are connected together end to end by means of angle bars g g, riveted on the bottoms a and flanged brackets h i riveted on the front and rear and bolted'together by bolts passed through the adjacent angle bars 9 g and brackets h i and transverse plates j of which one is indicated in Fig. 3 are placed between the opposed sets of angle bars 9 g and brackets h i to stiffen the sections when the nuts upon the connecting bolts are tightened. The connected sections of the carriage form a continuous box girder.

The connection of the connected sections to' the square of the self acting mule and the completion of the section most remote from the'square at the outer ends are effected in For example anin Figs. 2' and 3 but preferably extending over greater surfaces of the sections to which they are applied, may be provided upon the ends of the sections to adjoin the square and the "sections most remote from the square may be provided at the outer ends directed away from the square with metal plates of appropriate form attached by means of angle' bars or brackets. To the front I) of each section at the upper part is riveted a plate is with a flange Z inclined downwards to the rear to form a rest for the spindle rails or boxes 11 and readily removable for the substitution ofanother'if change in the position of the spindle rails or boxes m should be necessary at any time.

According to this invention in order that carriage bearers may be applied to a carriage for a self acting mule constructed as aforesaid, steel or other channel bars with parts of'the flanges made to extend as ears transversely "from the ends are provided to be applied with the flanges upwards, transversely on the bottoms of the sections of the carriage or carriage bottoms and riveted or adi 'antageously bolted at their ends to angle bar's orffianges riveted or otherwise secured to or provided on the bottoms of the sections orcarriage' and preferably made to extend 'al'onigthem or itsothat the channel bars any convenient form, such as screws, bolts or studs, attached to or serving for the attachment of thecarriage bearers are secured. Preferably to facilitate application of the rising screws if the holes for them should be accessible from only one side in use, these holes are formed large enough to allow passage of nuts or bolt heads or the like on the.

rising screws and communicating slots in which the shanks or like parts of the screws may be secured by means of nuts. In an alternative construction rising screws may be fixed in position on the channel bars by Channel bars to which ris-t spot welding. ing screws may be attached as aforesaid may also be attached in other ways to mule carriages or sections thereof.

In Figs. 1 and 2 n n are two steel or other channel bars. Each of the channel bars a has parts of the flanges made to extend as ears 0 transversely from the ends and one near each end and the other near the front is furnished with a hole and communicating slot to serve respectively for the passage of the head and the passage of the shank of one of the rising screws 29. A hole is formed in each of the ears 0. or flanges which are formed with holes along their length at equal intervals equal to the distance between the centre lines of the holes in the ears 0 at one end of either oft-he chan nel bars a and are riveted to the bottom a of'the section at the front and rear. The channel bars n are applied with their flanges upwards on the bottom a of thesection of the carriage and secured in position by means of rivets passed through :holes in the ears 0 and convenient holes in the flanges or angle bars {1. When the channel bars n have been applied to the bottom a of the section of the carriage and secured to the flanges or angle bars I] the heads of the three rising screws p are introduced through the holes into the space within the channel bars a and the shanks are slipped into the communicating slots and secured therein by means of the nuts 7 and the rising screwsp are adjusted and secured in position in the car- 9 q are angle bars riage bearers s in the ordinary manner for the section of the carriage to be supported in the manner requisite by the wheels of the carriage bearer 8. Other channel bars a like the two shown are applied wherever convenupwards on the lower surface of a carriage for "a self acting mule or sections of such a carriage according to this invention espe-.

cially when applied along with angle bars or flanges q and best of all with angle bars or flanges g with holes at equal intervals along their length, afford a very convenient means for the attachment of the rising screws p, for the connection of the carriage bearers s to the carriage.

According to this invention in order that bearing brackets for a tin roller shaft may be applied on a carriage for a self acting mule constructed as aforesaid, there are pro vided' on the carriage steel or other channel bars with parts of the flanges made to furnish at the ends, ears at right angles to the bars or in other positions convenient for the attachment of the bars. The channel bars are furnished with holesand communicating slots for the passage respectively of the heads and shanks of bolts so that bolts may be inserted if only one face is accessible in use, but if both faces are accessible in use simple holes may serve. The channel bars are applied with flanges downwards transversly on the top of or within the sections or body of the carriage and are riveted or bolted at their ends to sections or the carriage to which they are applied. Each channel bar is made to bear one of the bearing brackets for the tin roller to extend along a carriage and a block through or to which is passed or attached a screw for adjusting the bearing bracket lengthwise of the channel bar, bolts or studs for securing the bearing bracket and block to the channel bar being passed through the holes in it. Brackets secured to the channel bars by means of rivets or by means of bolts passed through the holes, either with communicating slots or simple holes as aforesaid or by other means maybe provided to afford screw threaded holes or other appropriate bearing for screws with lock nuts for adjusting and fixing the adjustment of the bearing brackets lengthwise of the channel bars. The channel bars provided in this way for carrying bearing brackets may be attached at any convenient place on the sections or body of a carriage either at the junctions of sections or elsewhere and serve to stiffen the sections to which they are applied.

Channel bars on which bearing brackets may be mounted as aforesaid may also be attached in other ways to mule carriages or sections thereof.

In Fig. 3 t is a steel or other channel bar with parts of the flanges made to extend as ears u transversely from the ends and in its central part provided with a hole and communicating slot to serve respectively for the passage of the heads of bolts 4) and the passage of the shanks of such bolts 41 and also with a bracket w riveted upon it to carry a set screw furnished with a lock nut. A hole is formed in each of the ears u. The channel bar If is applied with the flanges downwards on the top d of the section of the carriage and the ears u are riveted by means of rivets passed through the holes in them and corresponding holes in the upturned flanges Z), c, 0, f of the plates or sheets forming the section so that the channel bar t is secured in posit-ion. When the tin roller bearing bracket 1 shown which is of ordinary form, is to be applied to the channel bar t the heads of the bolts 1; for securing it in position are passed through the hole in the channel bar t so that the shanks are passed into the communicating slot and after the tin roller bearing bracket 3/ has been adjusted into position by means of the set screw 00 the nuts on the bolts '0 are tightened.

Other channel bars I? like that shown are applied wherever convenient on the section and elsewhere for the connection of tin roller bearing brackets.

' Channel bars applied with the flanges downwards on the top of a carriage for a self acting mule or on sections of such a carriage according to this invention afford a very convenient means for the attachment of tin roller bearing brackets to the carriage.
